Hi David,

great that you took the time to report this. Most of these warnings havebeen around sinc ethe merge of the NSXML branch and it would havehelped, if you had reported them earlier. The problem here is that onlypeople using clang and the pure non-fragile API can see these warnings.We now have at least three ways the ivars in base get handled and onlyon one of them these warnings were visible.Most of these are completely harmless, having a local variable named thesame as an ivar is inconvenient, but no real problem, but the use ofinternal (or worse _internal) needs to be removed. The alloc calls onthe wrong class are actually correct, but confusing and confusing codeis bad code, so I will remove them as well. Over all it is better toremove all compiler warnings, even if they are nonsense, that way newones are more visible.I will try to address all 142, please test again after the change andreport back.

Hi,

When compiling the new NSXML stuff for a modern deployment target (pure 
non-fragile ABI), I get a very large number (150 or so) of warnings, mostly 
about shadowed ivars.  A lot of these look like they are real bugs.

They've been there for a few weeks, and I was hoping that while people were 
actively working on these files they'd be fixed, but this appears not to be the 
case.

I've attached the complete list of warnings generated from these files,
